To ALL WHoM IT MAY eoNcnnN:

Be it known that I, A. KOMP, of the city, county, and State of New York, have invented a new and .improved Eyeleting-Machine; and I do hereby declare the following to be a. full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawing, forming part of this specification, in which drawing- V Figure 1 represents a sectional side elevation of this invention when the punch is up.

Figure 2 is a similar view of the same when the punch is down.

Figure 3 isa detached section of the punch and spring-catch, which acts on the guidepin in the interior of the punch.

Similar letters indicate corresponding parts.

The invention relates to a machine for fastening eyelets in paper, cloth, leather, or any other material of asimilar nature, the eyelets being placed in a hopper, from which extends a curved chute, said hopper and chute being secured to a segment, which oscillates on a pivot, and which connects with the lever that serves to impart motion to the punch in such a manner, that, by the action of said lever, vthe eyelets in the hopper are agitated, and caused to pass down into the chute, and furthermore, the mouth of the chute is withdrawn from undet'the punchat the proper intervals, leaving the punch free to force the eyelets through the cloth er other material, and to clinch them. The anvil on which the eyelets are clinched is provided with a projecting point, and it is surrounded with an elastic bed, in such a manner that the cloth or other material in which the eyelets are to be fastened, on being forced over the projecting point, is pierced, and then supportedby thev elastic bed, which offers sufficient resistance to permit the eyelet being forced through the hole made in the cloth or other 'material .by the projecting point, and which yields as the punch descends to clinch the eyelet.

The eyelets, on passing down through the chute, are reversed, leaving their ilanges up, and they arc taken from the mouth of the chute by a guide-pimwvhich is situated in the interior of the punch, and subjected to the action of a spring, which has a tendency to force it out of the punch. When pushed' in the guide-pin is retained by a spring-catch, which isautomatically released whenever the punch reaches its highest point.

To the side of the guide-pin is secured a Weak spring, which retains the eyelets on said pin until the punch forces the same off, and into the cloth or other material on the'anvil.

A represents a bed-plate, from which rises a standard, B, which forms the bearings for the principal Working parts of my machine.

From the front end of said standard extend two arms, C, which are perforated, to admit the punch D. This punch slides freely in the arms 0,'.and it is suspendedfrom a forked arm, E, which extends from the hand-lever F. The fulcrum of this hand-lever is on a pivot, a, which is secured in the lstandard B, and the front end of said hand-lever bears on the top of the punch D, so that, by raising the rear end of the lever, the punch is depressed, and by depressing said rear end, the forked arm Ecarries the'punch up to its horizontal'position, as shown in iig. 1 of the drawing. A weight or spring is made to act on the lever F, in such a; manner that the same, when left to follow its inherent gravity, assumes the position shown in iig. 1.

The eyelets to be operated upon by the punch are placed in a hopper, G, which is secured to a segment, H, that swings on apivot, b, :fastened in thestandard B.

i From the hopper. extends a chuteH, which is composed of two strips, placed in such a relative position towards each other, and towards the base of the chute, that the anges of the eyelets can catch under the strips, while the tubes of said eyelets project through the gap left between them, as indicated in red outlines in iig. 1.

The chute, however, is curved in such a manner that the eyelets, which enter the same from the hopper with their flanges down, are reversed, and brought under the punch with their anges up.

On arriving at the mouth of the chute, the eyelets are prevented from dropping out by a forceps, c, and by a supporting spring, d, said forceps being composed of two jaws of' thin spring steel, so that 'they yield, and allow the first eyelet to pass out of the chute at the proper intervals.

The segment II is connected by o, rod, d', with the lever F, se that, when the rear end of scid leveriis raised, the mouth ofthe chute swings buch from under the punch, und ut'the seme time, by actuating seid lever, c shaking motion is imported to the hopper and cjhute, whereby the eyelets are caused to enter said chute, and pass down in thesanie.

The punch D is bored out, to receive the guide-pin c. This pin is subjected to the action of :t spring, f, which has n tendency to throw the salue out to the position shown in iig. 1, and it (the pin) is provided with a. shoulder, y, which, when the pin is 'forced in against the action of its spring, catches over n. dog, 7L, which passes in through the side of the punch, ns shown in tig. 3, und which is subjected to the action ofc spring, z', thuthus o. tendency to force the come in towards the guide-pin e.

To the outer end of the dog 7i is secured :t heed, j, the inner edge oi which is churni'ered oii, und which acts against n com, c, whenever the punch arrives in its highestposition. When the heed strikes the cum, the dog 7L is drawn bueh, and`the guide-pin, being released, follows the action of its spring, f, and 'dies down to the position shown in iig. 1.

The com .7.: is secured to one of the arms C by u pivot, Z, and it cnn'be turned on this pivot by n. handle, m. When the handle is turned to the position shown in redeoutlines in fig. 1, the low portion of the cam k comes opposite the hend `7', and the guide-pin is not released, so that the punch can be worked up several times without causing seid guide-pin to ily out, und that the eyelets inthe hopper can be subjected to u violent agitation in cese they should foil to pass properly from the hopper into the chute. i

Then the cuni 7c is thrown into the position shown in black outlines in iig. 1, the guide-pin flies out whenever the punch husrcached its highest position, und posses through the eyele't in the mouth of the chu-te, and if therein' end of the hand-lever is raised, the chute recedes from under the punch, the punch descends, and the eyelet, through which the guide-pin has passed, is retained thereon by o. weak spring, 1t, which is u ttztched to the side of said guide-pin, as shown in iigs. 1 and 2 of the drawing.

'Ihe cloth or other material into which the eyelet is to be fastened is placed on the nbvil I, which is secured in the bed-pluto A, underneath vthe punch D. i It From the centre of this anvil rises the point 0, and as the cloth or other material is forced over this'ipont, a hole is mode in the someto receive the eyelet. l i

The cnril I is surrounded by u yielding rest, J, which is supported by :t spring, i), and which, when left to follcw'he action ot' this spring, rises somewhat above the clinching-surfuce of the anvil, and supports the cloth or other materiel in which the eyelet is to he secured.

The bottom end of theV guide-pin e is countersunk, to admit the end of the point o, und as the punch D is depressed by the lever-F, the guide-pin, on striking the pointe, recedes, and the cyelet, suspended from 'said guide-pin', Vis forced through the hole previously opened in the 4cloth or other material hy the point o. During this operation, the rest J supports the cloth or other materiel, and the spring p, supporting this rest, is of such power that it does notyield by the pressure required to force the eyelet through the hole in the cloth or-other material, but when the punch bears further down upon the eyelet, the rest yields,and the' eyelct. being compressed between the punch and the anvil, is clinched, as shown in 2 of thedrawing.

By these means, the operzttionof inserting'the eyelets'into the cloth or other material, and that of clinching the sume nt'ter they have been inserted, uro combined in a. simple and effective manner, and the edge of the hole opened in the cloth or other materiali by the point o is gathered up between the flanges of the clinched eyelet, so that euch eyelet taires a; firm hold, und is not liable to come 01T, unless subjected to very severe use.

Hoving thus described my invention, what I claim as new, and desire to secure by Letters Patent,is

l. The friction-spring il, on the guide-pin e in the punch D, substantially its und for the purpose described.

2. The self-acting dog L and com L, in combination with the guide-pin e and punch D, substantially as and for the purpose set forth.

The yielding rest J, in combination with the :tnvil I und punch D, substantially as und for the purpose set forth.
